In addition to NDF, new improved methods for total dietary fiber and nonstarch polysaccharides including pectin and beta-glucans now are available and are also of interest in rumen fermentation.

The Cornell Net Carbohydrate and Protein System (CNCPS) has a submodel that predicts rates of feedstuff degradation in the rumen, the passage of undegraded feed to the lower gut, and the amount of ME…

A new liquid marker, cobalt-ethylenediamine tetraacetic acid (EDTA), and two solid markers, chromium (Cr) and cerium (Ce) mordanted plant cell walls, were investigated and Co- EDTA was found to be comparable to Cr-EDTA.
A net carbohydrate and protein system for evaluating cattle diets: I. Ruminal fermentation.

- 1 November 1992
The Cornell Net Carbohydrate and Protein System (CNCPS) has a kinetic submodel that predicts ruminal fermentation and the protein-sparing effect of ionophores is accommodated by decreasing the rate of peptide uptake by 34%.

The Cornell Net Carbohydrate and Protein System (CNCPS), a mechanistic model that predicts nutrient requirements and biological values of feeds for cattle, was modified for use with sheep. Published…

- 1 November 1992
The Cornell Net Carbohydrate and Protein System (CNCPS) has equations for predicting nutrient requirements, feed intake, and feed utilization over wide variations in cattle, feed carbohydrate and protein fractions and their digestion and passage rates, and environmental conditions.
Evaluation of a mathematical model of rumen digestion and an in vitro simulation of rumen proteolysis to estimate the rumen-undegraded nitrogen content of feedstuffs

- 1 November 1983
The UDN values estimated from simulated rumen proteolysis and those determined in vivo for twelve mixed diets were in close agreement and can serve as a simple, rapid and sensitive method to estimate UDN in a variety of feedstuffs.
A Nutritional Explanation for Body-Size Patterns of Ruminant and Nonruminant Herbivores
- M. Demment, P. V. Van Soest
- BiologyAmerican Naturalist
- 1 May 1985
Calculations suggest that sufficient intake of a high-fiber diet cannot be maintained to provide the energy necessary to support larger body sizes, and changing body size is postulated as a mechanism for differentiating the feeding requirements of herbivores.
Prediction of ruminal volatile fatty acids and pH within the net carbohydrate and protein system.
- R. Pitt, J. S. V. Van Kessel, D. Fox, A. Pell, M. C. Barry, P. V. Van Soest
- Chemistry, MedicineJournal of Animal Science
- 1996
In a review of literature data, effective NDF (eNDF) provided a better correlation with ruminal pH than forage or NDF, and individual VFA fractions were inadequately predicted.
Effect of carbohydrate limitation on degradation and utilization of casein by mixed rumen bacteria.
- J. Russell, C. Sniffen, P. V. Van Soest
- Biology, MedicineJournal of Dairy Science
- 1 April 1983
Mixed rumen bacteria were incubated in media containing salts, ammonia, vitamins, volatile fatty acids, sulfide, and casein, and Nitrogen-15 labeling studies indicated that 66% of the cell nitrogen was derived directly from casein at all rates of carbohydrate addition.
